In standard trim they are perfect for the UK's roads, maybe you just need to renew the dampers. If you want it to handle like its on rails then get coilovers and get them set up by a proffesional, or even get some adjustable dampers and keep you springs.
Saw your car in Bourne woods a while back, I was with a guy with a orange rover. Also saw you at donnington on the camp site down the bottom.
